"Stick to what got (Wilson) in the headlines, not baseball," Jackson said Tuesday, per CSN Chicago. "Twenty-five or 30 years ago when I did it, I'm not trying to say anything negative about other athletes, but the talent pool wasn't that deep. In this day in age, with all the high-tech training, computer-engineered workouts and the proper food and diet, if you try to concentrate on two sports, I guarantee you're going to ride the bench in both because the talent is that deep. Stick to whatever sport you're comfortable with and let everything else go."

The point is a salient one from the most famous two-sport athlete. Jackson wowed fans with his prowess on both fields of play before injuries derailed his careers in the early 90s.

Wilson's attendance at Rangers camp came with nod to the PR move of bringing in a Super Bowl champion, who happened to be a former minor-league second baseman. But the 25-year-old quarterback drew some headshakes earlier this month when he responded, "you never say never," to a question about playing both sports.

Jackson would suggest Wilson just say never. In fact, Jackson admitted he probably couldn't play both sports in today's climate.

"I probably couldn't, no," Jackson said. "Just because the talent pool is that deep now. If my kids want to do both sports -- 'No. No. No.' ... If you try to do both you're going to be riding the bench in both. You'll never get to that level that you want to get to if you split your time between multiple sports."
